The Hobbit: The Desolation of Smaug
There's danger, more danger, and some Legolas in the latest trailer for the second installment of the Hobbit trilogy. The sneak peak was released as part of a worldwide fan event that director Peter Jackson held earlier this week, as Bilbo Baggins continues on his adventure with the dwarves to recover their gold back from evil dragon Smaug (voiced by a grizzly Benedict Cumberbatch).

The Hunger Games: Catching Fire
The new TV spot for The Hunger Games: Catching Fire is brought to us by Subway (oh, sweet irony...) and features a new track from Christina Aguilera called 'We Remain'. This trailer is less action based, and more focused on the relationships between the principal characters. The film opens worldwide on November 22nd.

RoboCop
The latest trailer for Jose Padhila's remake of the '80s classic features Samuel L Jackson's villainous Pat Novak asking the question: "Why is America so robo-phobic?" Packed with action, the trailer sees the transformation of Alex Murphy (Joel Kinnaman) into RoboCop. The film also stars Michael Keaton, Abbie Cornish and Gary Oldman.

The Railway Man
Colin Firth stars in this adaptation of Eric Lomax's memoir centred around his experiences before, after and inside a Japanese prisoner of war camp. The emotional new trailer for The Railway Man deals with Lomax's search for the interpreter whom he views as responsible for how he was treated in the camp. The film also stars Nicole Kidman as his wife Patti, and Stellan SkarsgÃ¥rd as his best friend Finlay. Jeremy Irvine plays the younger Lomax.
